[FEATURE] Support markdown TOCs in Populate

[fusedFET]

Hello!

Describe the bug

Consider following index.md fed into the 'populate' tool:

# PCBA Manual

- [PCBA Manual](#pcba-manual)
  - [PCB Top assembly](#pcb-top-assembly)
  - [Conclusion](#conclusion)

## PCB Top assembly

First step in the assembly is the populating of the TOP face.

- [[front | ]] This is the front side of the board we are populating

## Conclusion

This is the end of the demo.

Note the auto-generated Table Of Contents by vscode below the main title.

To Reproduce
Run the populate tool on this index.md.
The rendered results will be:

# PCBA Manual


#### [PCB Top assembly](#pcb-top-assembly)

![step](img/populating_1.png)

#### [Conclusion](#conclusion)

![step](img/populating_2.png)

#### [PCBA Manual](#pcba-manual)

![step](img/populating_3.png)

## PCB Top assembly

First step in the assembly is the populating of the TOP face.


####  This is the front side of the board we are populating

![step](img/populating_4.png)

## Conclusion

This is the end of the demo.

The tool seems to see the 'populate' patterns in the TOC. It tries to render unexpected images.

Expected behavior

The generated MD to be:

# PCBA Manual

- [PCBA Manual](#pcba-manual)
  - [PCB Top assembly](#pcb-top-assembly)
  - [Conclusion](#conclusion)
 
## PCB Top assembly

First step in the assembly is the populating of the TOP face.


#### This is the front side of the board we are populating

![step](img/populating_1.png)

## Conclusion

This is the end of the demo.

Hi @fusedFET !
Did you read the docs?

each list item is considered as a single step in populating and will generate an image.

And this is exactly what you say you are getting!

The above patch adds some basic support for this TOC case. Check if it works for you.
